Peripheral Vascular Disease

The InSpectra™ StO₂ Tissue Oxygenation Monitor has not been cleared by the FDA for use in diagnosing peripheral vascular disease. Additional clinical studies are required to establish the value of these measurements in assessing patient status relating to peripheral vascular disease.

A study comparing patients with peripheral arterial disease (PAD) to normal patients demonstrates the potential value of the InSpectra™ System for assessing compromised circulation.

The InSpectra™ StO₂ Tissue Oxygenation Monitor provides a noninvasive, continuous, real-time, and direct measurement of hemoglobin oxygen saturation in tissue (StO₂), providing trauma teams the ability to measure tissue oxygen saturation and monitor it during resuscitation. It is the only perfusion status monitor designed for trauma environments. The InSpectra StO₂ Tissue Oxygenation Monitor uses near infrared light to illuminate tissue, and then analyzes the returned light to produce a quantitative measurement of oxygen saturation in the tissue's microcirculation.

The StO₂ Trauma Study researched the role that tissue oxygen saturation monitoring could play in hemorrhagic shock and resuscitation. Study results demonstrate that StO₂ measurements less than 75% may indicate serious hypoperfusion in trauma patients and that StO₂ functions as well as base deficit in indicating hypoperfusion in trauma patients.
